Diamond Warranty is a Pennsylvania-based vehicle service contract provider founded in 2006. Operating through a nationwide network of dealerships, they offer several levels of protection designed to help drivers manage repair expenses after factory warranties expire. Their plans range from basic powertrain coverage to broader exclusionary contracts, with options for used vehicles, certified pre-owned models, and drivers seeking long-term protection.
Many contracts are backed by AmTrust Financial Services and may include benefits such as roadside assistance, rental car reimbursement, and trip interruption coverage. The company focuses on dealer-distributed service contracts rather than direct online sales, which means pricing and contract details often vary by vehicle and dealership. Diamond Warranty maintains an A+ rating from the Better Business Bureau, though they are not BBB accredited.
Customer feedback across review platforms is mixed, with experiences ranging from praise for responsive representatives and straightforward claims to complaints involving coverage disputes and communication challenges. With nearly two decades in the industry and a diverse selection of plans, the provider offers several features worth examining more closely before making a decision.
Established in 1986 and based in Mountain Home, Arkansas, Route 66 Extended Warranty, an Auto Services Company, Inc. subsidiary, stands out in the national extended auto warranty sector. The company aims to provide "Peace of Mind" through comprehensive mechanical breakdown coverage. Advantages of Route 66's extended warranties include instant coverage, no deductibles, nationwide accessibility, and 24-hour emergency roadside assistance. However, drawbacks include limited plan transparency, exclusive availability through financial institutions, and the absence of an online quote service. The company offers three plans—First Street, Main Street, and Easy Street—ranging from $1200 to $3500. Customer reviews vary, offering both positive and negative feedback. They highlight the positive experience of timely reimbursement and express concerns about denied claims and challenges with customer service. The company operates under Auto Services Company, Inc., which holds an A+ rating on the Better Business Bureau. Despite some limitations, Route 66 Extended Warranty remains a comprehensive option for reliable and tailored vehicle coverage. The company caters to a diverse audience, focusing on used car owners, frequent travelers, and new vehicle owners looking to extend factory warranty coverage.
